An ex-assassin from Nether Gate, Sagiri was trained at an early age to follow orders and kill, even before understanding the preciousness of human life. Nether Gate's chief trainer of assassins believed that having a little girl smile at the target would get them off their guard. Because of this, Sagiri was trained to smile all the time, no matter how she felt.
One of the many people Sagiri killed as an assassin was Nakula's father, a hard-line Armes chieftain.

After Nether Gate disbanded, Sagiri was taken in by Oboro and Shigure, and went into business with them. They started a detective agency, and Sagiri worked as an investigator. She often motivates the lazy Shigure to do his job.

She meets the Prince when he hires Oboro to investigate Lord Barows's actions during the Lordlake rebellion. She tails Norden and brings him to the ship, and he confesses afterward.

When Oboro joins the Prince's army, Sagiri opts not to fight. She apologizes to the Prince, but she doesn't want to kill people anymore. Oboro accepts this, but allows Sagiri to stay with them. Even though not an official member of the Prince's army, Sagiri helps in investigating, and in setting a trap per Lucretia's request in Doraat.

It isn't until Nakula, seeking revenge for his father, finds Sagiri. Shigure and Oboro defend her, and Nakula agrees to help the Prince, since Nether Gate is now an army working for Godwin. He tells Sagiri he will deal with her later, and she accepts, and will not run anymore. She joins the Prince's army officially.

Sagiri's smile does not fade from the eight years after Nether Gate disbands. Although, after the war ends, Sagiri returns to the detective business, her smile slipping every so often. - Matt620(article), Basel (image)
